Unity Cloud Build Shaders 3.0 for Windows: Mastering the Basics

In this tutorial, we will explore the world of shaders in Unity, specifically focusing on surface shaders and shader graphs using Unity 2020.3.6f1. We'll also learn how to make our function time-dependent, creating an animating graph that showcases mathematical formulas using game objects.

For those new to Unity, this is the second tutorial in a series aimed at teaching the basics of working with Unity. In this article, we will delve into the world of shaders and explore their capabilities, particularly in relation to surface shaders and shader graphs.

One of the key features of Unity's shader system is the ability to create complex effects using simple code. This is achieved through the use of surface shaders, which are a type of shader that generates a number of passes behind the scenes. By combining multiple surface shaders or adding manually written passes, it is possible to create more complex effects.

However, there are limitations to this approach. If you find yourself needing to split your shader into multiple passes, it may not always be possible to fit everything into one pass. In these situations, it is generally possible to split the shader into multiple passes using the UsePass function.

Another important aspect of shaders in Unity is the ability to optimize them for performance. One trick to save interpolators, which are used by shaders to manipulate texture coordinates, is to use a single UV* variable in your surface shader input. This can help reduce the number of interpolators needed and improve overall performance.

In addition to optimizing shaders for performance, it's also important to keep an eye on the number of interpolators available to your shader. By default, Unity's shaders have access to 8 interpolators, but by compiling your shaders to shader model 3.0 using the #pragma target 3.0 directive, you can increase this number to 10.

When it comes to working with normal maps in your shaders, there are a few things to keep in mind. One common issue is that main texture and normal map usually use the same UV coordinates, so it's a good idea to use one UV* variable for both textures.

Another common issue that can burn up interpolators is per-pixel normal mapped reflection, which requires 3 interpolators to pass tangent space vectors. If you find yourself running out of interpolators, there are a few tricks you can try to save them. For example, if you have multiple textures and know they don't need different UV scale/offset, you can use the same UV* variable for all of them.

In conclusion, shaders are a powerful tool in Unity that allow developers to create complex and visually appealing effects. By mastering the basics of surface shaders and shader graphs using Unity Cloud Build Shaders 3.0 on Windows, developers can take their projects to the next level and create stunning visuals that engage and immerse players.
